INTERNAL-COMBUSTION NGINE;

To all whom it may concern Be it known that If PnRoivAL Teams HoUs'roN, a subject of the King of England, residing in London, England. have invented certain new and useful Improvements in Internal-Combustion Engines, of which the This invention reLtes-to improvements in the connecting rod and a reciprocating movement. In'such an engine it" has been proposed to mount the bearingsfor theends of the g'udgeon pin-which connects] the small end of ton' i'n such a manner inkthe piston that although the bearings' reciprocate as one with it the piston can turnrelative'l y to-t'he said The turning movement of the piston was effected b v an extension provided on the small end of the connecting'rod and. 0peratively connected 'with the piston.

According to this"inv' ention aball and socket i ointi between the: connectingrod and the piston" 'is 'combined with" an extension on} the. small end of theI'c'onnecting mod, which extensioncouples the rod to thepiston through bearings each permitting combined sliding a'ndtiirning movements. The extensionon thesinall end of the connecting-rod can proiect laterally therefrom and have its end in sliding and turning engagement with block which has sliding and turn-tu boatransverse to those piston. f I
